8TEN Deck Rebuild Kit Blade Spindle Belt Idler for Cub Cadet XT1-LT46 XT2-LX46 Troy Bilt Super Bronco 46-Inch 942-04244A

What It Is

This is a complete deck rebuild kit for 46-inch cutting decks on select Cub Cadet and Troy-Bilt lawn tractors. It includes replacement blade spindles, belts, and idler pulleys needed to restore worn-out mower decks to like-new cutting performance.

Fitment & Compatibility

• Deck size: 46-inch (LT46, LX46, 46A models)
• Fits: Cub Cadet XT1-LT46, XT2-LX46, Troy-Bilt Super Bronco 46-inch, and other models using OEM part 942-04244A
• Check before buying: Measure your deck width (center-to-center of outer blade tips) – must be exactly 46 inches. Verify your existing spindle bolt pattern matches the kit (typically 3-bolt, 4-inch spacing). Confirm your belt length (look for a stamped number on the old belt) – this kit replaces belts approximately 92–96 inches long.
• OEM cross-reference: Replaces Cub Cadet 942-04244A, 918-04244A, and Troy-Bilt 942-04244A. Not compatible with 42-inch or 54-inch decks.

Key Things to Know

• Quality: 8TEN is an aftermarket brand; these parts are generally comparable to OEM but may use slightly thinner metal on pulleys. Expect 2–3 seasons of heavy residential use.
• Installation difficulty: Moderate to difficult – expect 2–3 hours if you’re handy with hand tools. You’ll need a socket set, torque wrench, and possibly a puller for stubborn spindles. Watch for hidden bolts under deck baffles.
• Common gotchas: The belt routing diagram in the box is sometimes unclear – take a photo of your original belt path before disassembly. Spindle bearings are pre-greased but not sealed; apply additional grease on installation. Check that all four spindle bolts are the same length – some kits ship with mixed lengths.
• Included parts: 3 spindles, 2 belts (one deck drive, one PTO), 2 idler pulleys, 4 spindle bolts, and washers. You may need to reuse your original pulley spacers.

Should You Buy It

Buy this kit if your 46-inch Cub Cadet or Troy-Bilt deck is vibrating, cutting unevenly, or has noisy spindles, and you want a single-purchase restoration without hunting for individual parts. Skip it if you need OEM-level durability for commercial use or if your deck is smaller than 46 inches – in those cases, buy separate OEM spindles and belts.
